This was a good buy, easy to assemble and sturdy, the dog house is in use  in Saskatchewan Canada, and provided waterproof and wind proof shelter for the dog and the cat during some nights with temperature of -50c  with the aid of a heated pet pad during the winter, it is easy to clean with the clips to remove the roof and sides,, the only addition made was a heavy stone placed inside to weight it down during strong winds, and the dog and cat love it too .
